Abstract

L'invention concerne un élément générateur d'ions (10) comprenant au moins une première partie de décharge (12) destinée à générer des ions positifs, et au moins une deuxième partie de décharge (13) destinée à générer des ions négatifs. Ces première et deuxième parties de décharge (12, 13) sont montées ou imprimées sur un corps diélectrique (11). La première partie de décharge (12) est pourvue d'une paire constituée par une première électrode de décharge (12a) et une première électrode d'induction (12b). La deuxième partie de décharge (13) est pourvue d'une paire constituée par une deuxième électrode de décharge (13a) et une deuxième électrode d'induction (13b). Les première et deuxième électrodes de décharge (12a, 13a) sont disposées sur la surface du corps diélectrique, et les première et deuxième électrodes d'induction (12b, 13b) sont enterrées dans le corps diélectrique (11). La première et la deuxième partie de décharge (12, 13) sont éloignées l'une de l'autre indépendamment, sur le même plan que le corps diélectrique (11). Cette structure permet de supprimer la neutralisation des ions générés, et d'émettre efficacement des ions positifs et négatifs, ce qui améliore l'efficacité de la génération ionique.
